According to General Motors E-Flex spokesman Rob Peterson, the automaker has reached an agreement with the California Air Resources Board (CARB) that would see the
2011 Chevy Volt get a unique classification different from other current hybrids. This new classification takes into account the fact that the Volt's 40-mile battery range allows it to complete the bulk of the emissions and economy test procedure without ever running the engine, which would likely give it a mpg rating of 100 mpg or better.
This is problematic for the EPA, which considers dual-power vehicles like the series hybrid Volt no different than a parallel hybrid like the Prius. Currently the EPA is expecting the Volt to complete the test cycle with a charged battery, which means the engine would have to run a lot more and essentially kill the charge sustaining control plan. According to Peterson, GM is still a long way from reaching an agreement with the feds on how to test the Volt, despite what the
Detroit Free Press says. However, having CARB consider the Volt essentially an electric car is certainly a bargaining chip in GM's favor.

Inside Line kicked up a dust storm yesterday by claiming that the 2011 Chevy Volt
could not recharge its batteries while driving using its on-board, range-extending 1.4L gas engine. 40 miles of electric-only drive was it, and then the battery packs become "400 pounds of uselessness" was what IL said. They got this impression from a press release issued when the
production Volt was unveiled to the public, which stated that the gas engine could only "sustain" the battery pack's charge and not increase it. GM got its communications crossed and apparently confirmed IL's take, but has thought about it some more and today reconfirmed what we initially thought was true, that the Volt's gas engine
can recharge its batteries while underway.
What the Volt's gas engine
can't do is completely recharge the battery pack to its full capacity. Rather, when load conditions are light the gas engine will send surplus electrons to the battery pack, which will also be receiving extra charge from regenerative braking, as well. That sounds about right to us, as we've always been told that constantly charging a battery to its maximum will shorten its life, as the optimum charge range is usually between 20 and 80 percent, not completely drained and not completely charged. GM is determining right now just how much it wants to let the gas engine charge the Volt's battery pack, but rest comfortably knowing that your future Volt won't be carrying around 400 lbs. of uselessness when the charge runs out.

Hyundai is headed to the
Paris Motor Show with a bevy of environmentally friendly models and concepts. In addition to bringing along production-intent vehicles like the new i20, Genesis Coupe and Genesis sedan, the automaker will showcase two new concepts that will also carry its blue theme. Remember,
blue is the new green. Anyway, the i20 blue features aero tweaks and low rolling-resistance tires in order to improve its efficiency, but it's the Santa Fe hybrid that's a bit more interesting. That new model features an electric motor that puts out 30kW of power along with a 2.4-liter four cylinder engine. Both powerplants feed their power through a six-speed automatic transmission with revised gear ratios optimized for fuel savings. A 270V lithium-polymer battery pack sends the juice to the electric motor, and it all adds up to 38 mpg in the U.S. and carbon emissions of 148 g/km. We'll be in Paris to see these things up close and personal, so stay tuned.
